Silicone release liners and tear strips can be applied cost-effectively and efficiently to a wide variety of shipping packages, such as shipping boxes, corrugated envelopes, courier bags, and envelopes, using Robatech’s adhesive application solutions. It does not matter whether these are made of corrugated cardboard, solid cardboard, paper, or film.
Different system configurations are used for the application of silicone release liners and tear strips. Both work with PSA adhesive.
The adhesive application systems glue energy-efficiently and reliably, keeping your operating costs low. Thanks to open interfaces and standardized Fieldbus protocols, the application solutions can be easily integrated into existing and new systems. Control is flexible:
The application of silicone release liners to shipping packaging depends on the respective substrate.
In the first step, a coating nozzle applies a precise, narrow strip of PSA hot melt adhesive to the lid flap or the lid of a package. In the second step, an applicator (partner company) places a silicone paper on the applied hotmelt strip with millimeter precision. The silicone strip is slightly wider and longer than the applied adhesive. This has two advantages:
In the case of shipping pouches made of film, a coating nozzle applies a narrow strip of PSA hotmelt to the unwinding silicone strip. The adhesive is applied intermittently so that adhesive-free gaps are created. Next, the silicone strip is glued on the continuous film. Later, both materials are cut at one of the adhesive-free gaps, and the shipping pouch is finished.
Robatech’s adhesive application solutions produce high-quality silicone release liners.
